Once one third of Disney band The Jonas Brothers , Nick Jonas, 22, is back all moody and sexy with a 'dark pop and R&B' album. It's a far cry from his goodie-two-shoes days of purity rings. Nick has 'closed the boy band chapter', but don't sob, because, well, look at him now. The ring's off, ( sex is an important part of his life ) he's grown up and we are very pleased with the transformation.

The Jonas Brothers were such good boys. Were you ever rock ’n’ roll?

There were a few things… We crashed a golf cart once, which was pretty wild. And a hotel room. We were horsing around and managed to break the floorboards. We covered it up with a rug. We weren’t busted.

Fans of the Jonas Brothers were, erm, insane…

We’ve had fans hop in the back of vans and travel with us for miles, then all of a sudden we would hear them. That was kind of frightening. For them and for us! But the fans have chilled out now… The gay part of my fan base has opened up in a huge way. I’ve made a big effort to open up and accept that.

Yes, we saw you in Flaunt magazine. How exactly have you buffed up so much?

I love getting in the gym and feeling healthy. I buffed up for a TV project called Kingdom. I played a fighter, so I put on 15lbs of muscle for the role and I liked it. In reality, I don’t like working out. I’m in there thinking, ‘This literally sucks.’ But I like the results, so I’ve kept it up. I have a trainer who pushes me.

Justin Bieber is buff now. Do you see him as competition?

Is he buff?

Not as buff as you, Nick…

OK, good. I haven’t seen him in person for a long time. In pictures he has a lot of tattoos.

You go out with Olivia Culpo - Miss Universe. That’s quite an achievement…

My girlfriend is amazing and we’re very happy. My fans have accepted her too. I’m willing to be open about relationships for the first time. I always thought I shouldn’t talk about it and now I know that’s strange. I look at pop bands dodging questions about girlfriends and think that’s just dumb. You are allowed a girlfriend.

You’ve dated a lot of famous women (Delta Goodrem, Miley Cyrus, Selena Gomez, the list goes on), are you still in touch with them?

I think it’s all on good terms. I’m fine. I haven’t spoken to Miley in quite a long time. Not in a bad way, but we all roll in different circles now. It’s been years since we all worked together. But she’s a very smart businesswoman, good on her! I’m sure she’ll have a flourishing career.

If it all went away tomorrow, what would you miss about being Nick Jonas, pop star?

Restaurant reservations. Places will say no, but if you turn up and they see you, things can change. That can be convenient.
